Sierra Coil Lead Wire 18-28100, 12 Inch, 90 Degree Male Distributor End to 90 Degree Female Coil End

The Sierra Coil Lead Wire 18-28100 is a copper ignition coil lead built to carry current from the ignition coil to the distributor on marine engines with a traditional points-and-coil ignition setup. It measures 12 inches long and is configured with a 90 degree male connector on the distributor end and a 90 degree female connector on the coil end, matching the exact routing angle these engines require so the lead sits flush without kinking or straining the terminals.

Copper construction provides reliable electrical conductivity for consistent spark delivery, which is essential for dependable ignition performance in a marine environment. Because coil leads are a wear item exposed to heat and vibration, replacing a cracked or corroded lead with this Sierra 18-28100 helps restore proper coil-to-distributor connection and ignition reliability. Note that Sierra also offers 18-28101 (female distributor end, female coil end) and 18-28102 (male distributor end, 180 degree male coil end) as separate part numbers, so confirm the connector configuration needed before ordering.
